The Broadcom DSL chipset do not usually synch as well (rate) as well as the MediaTeK chipset that is in you DSL-AC52U
But DSL-AC88U should be much more stable, maybe an option to change your SNR values, can you give us a screen copy of your DSL Settings page? so we can see what is happening?
Is Annex M (ADSL2+ M) your normal choice for your ISP in Spain, I also remember reading that in the early days, another user (babis3g) had issues with ADSL and the DSL-AC88U, I will drop him an email and see if he can advise ?
